Y, fourth idler 21 mounted between arms 22 of a .110

yoke mounted on shaft 23. Spring 24, by means of a bell-crank arm 22a, integral with arm 22, gives the two belts 17 a constant tension and in sures their friction contact with the drum 16, as is clearly shown in Fig. 1. The shafts 3 4 5-6 each carry two sprockets Srl-3b; 1a-4b; 5a-5b and 6er-6b respectively. On these sprockets are mounted chains 25-25a and 26-26a. Between the two top chains 25 and 25a, see Figs. 2 and 3, channels 27 are suitably secured thereto with their longitudinal axis parallel to the major axis of the machine.

Likewise, at the bottom, channels 28 are also secured in like relation. The sprockets are so keyed to their respective shafts that the upper channels 27 are in exactly vertical alignment with the lower channels 23 so that the advertising cards, as indicated by 29, can be freely and easily inserted therein without any attachments whatsoever and may be kept in a substantially vertical position in respect to the front and rear windows, as is indicated in 30 and 3l. In this manner, the cards are properly spaced and inserted two in each channeLback to back, and as the machine operates, they are progressively advanced by the magazine which is composed of the upper and lower series of card sustaining channels, and in this manner progressively recede from the rear window and move towards the front window in predetermined synchronism with the entire machines mechanism, as will be now fully explained.

A card kicker arm 32, fulcrumed at the top of the machine by pin 32a and actuated by link 33, the lower end of which is guided by its slotted end 33a, a roller 34 riding on cam 35 which is secured to shaft 36 gives the initial motion to the two cards contained in the upper and lower synchronized channels nearest to the front window 30. By pushing the cards, which contact with the pin 32h on the end of kicker arm 32, -as is clearly seen in Fig. 1. The pin 32h thus pushes off the card from the channels past the guides 37 and between the two friction belts 17 and the drum 16. It is to be noted that the kicker arm 32 passes through the opening 52a in partition 11 and the spokes on gear 52 escape contact with the kicker arm due to predetermined meshing of the gear together with its relative slow speed. Arm 32 in Fig. 4 is shownI passing through the opening 52a. l

In like manner, another card pusher element 38, see Fig. 2, which extends across the magazine and is guided in frames 10 and l1 and terminates as is shown in Fig. 6 in a bent hook member 38a and is actuated by bell-crank arm 39 and link 40 which likewise contains the guide slot 40h riding on shaft 36 and is actuated by cam 42, suitably secured to shaft 36. Cam 42 isr so timed in respect to the cycle of the machine that hook 38a is in a forward position, see Fig. 6, and out of contact with the cards as they are in transit around the friction drum 16 but hook 38a moves backward by the setting of the cam 42 at the proper moment as and when the cards clear from the drum 16 so as to push the rearmost edges of the two cards on to the rearrnost magazine channels 27 and 28 which are now empty and ready to receive the cards in question. Y

It is to be noted that the hook 38a contacting with the respective rear edges of the cards, now

' loosely carried and sustained by guides 50 and the channel members 27 and 28, are in this manner necessarily re-aligned, one in respect to the other, after they leave thefriction'drum as they vin .each magazine compartment.

are pushed into place on to the sustaining maga; zine channels.

Referring to Fig. 5, the main drive shaft 12 has a pinion 51 meshing with the large gear 52 which turns on a bearing 53 sustained by frame member 11, see Fig. 2. A small gear 54, fastened securely to the rear of gear 52 meshes with the idler gear 55 which in turn engages the gear 56, to which gear is secured on arm member 57 with a cross pin 58 inserted in its outermost extremity. This pin in its relatively slow rotation asy reduced in revolutions per minute, by the above mentioned gear train periodically meshes with a recess 58 on disk 59 which is secured to shaft 6, on which is carried sprocket 6av and on which chain 26a engages. In this manner, through a conventional form of Geneva-stop-motion comprising disk 59 and the arm 57 with its engaging pin 53, an intermittent motion of the proper sequence and timing is given to the magazine with its transverse upper and lower card supporting channel members. The magazine is stationary as and 'when the kicker 32 and the pusher 38, respectively, push oiT and pull on the cards from and to the magazine, but moves forward in proper degree as and when the two cards have been deposited on to the rearmost channel members of the magazine by pusher 38. The lever 60 with its locking roller 62 and the spring 61 insures the magazines mechanism remaining stationary until the slowly rotating arm dictates its predetermined movement, as above described.

From the foregoing description, the operation of our invention is very readily seen. The magazine being filled with cards, two placed in each corresponding upper and lower channels in the magazine, the most rearward channel being kept purposely empty of cards, the machine is started into motion. The kicker 32 pushes the cards in the frontmost channels forward in friction contact with the drum 16 wherein the cards are engaged between the belts 17 and the drum 16, and as and when the cards leave the friction contact ofthe same, the pusher arm 33a, Fig. 6, pushes them forward re-aligning their respective rearmost edges and carrying the cards in proper position on to the empty top and bottom rearmost channels of the magazine. The magazines mechanism now comes into action advancing the cards in all their respective upper and lower channel sustaining positions forward toward the front window to the extent of one channel segment on the conveying sprockets. The machine has now arrived in its operation to its initial position previously described, and this cycle is again rev peated.

This machine operates with great smoothness. The movements are gradual in their acceleration and deceleration and cause no injury to the unprotected loosely sustained advertising cards.

Great emphasis is placed by us on the fact that this machine displays cards as are now supplied by the advertising trade for stationary advertising, and in this manner, its commercial value is greatly enhanced for the reason clearly brought out in the specications and in contrast to the prior art. It is furthermore pointed out that a standard commercial card, if printed on both sides with advertising matter, can be put into our machine without attachment or addenda of any nature and will function perfectly in lthe machine `iust as the two separate cards placed back to back I Finally, no groups of cards in any magazine division or single Lesage? card, if placed therein, ever contacts with another group of cards or card during their or its complete cycle through the machine. This valuable feature reduces wear by chaflng contact of the paper display placards or cards.
